JAMES WALKER, OF NEW YORK, N. Y.

GONG-BAELL.

SPECIFICATION forming part of Letters Patent No. 257,791, dated May 9, 1882. Application filed Aprilfi, 1882. (No model.)

relating to Gong-Bell Supports, of which the following is a specification.

My invention relates to gong-bells for clocks and the like; and the novelty consists in the construction, arrangement, and adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

The objects of the invention, among others,

.are to have the device occupy a minimum of space, and when in position to lie close to the bell-support bearing, and to prevent loss in the length or strength of tone due to the faulty transmission of vibrations.

I have learned that devices of this character, when made of several pieces, and of metals havin g different powers of vibratory transmission, fail to give the power, brilliancy, and length of tone which is desired, and that the joints in such constructions serve to weaken the sound and deaden the tone by destroying the uniformity of the vibrations.

My invention consists essentially in an ordinary volute gong, welded, soldered, or brazed firmly to a head or hearing, which is by a screw firmly attached to the body of a support or bracket. The bearing-surfaces between the gon g-head and the body of the support are suffioient to insure the uniform transmission of the vibrations. The support is made of such bell-metal as will best conduce to the full transmission of the vibrations, and consists of the body, to which the gong-head is secured, and a spiral shank, which terminates in a perforated bearing-plate, which is adapted to be secured by screws to the back of the clock or the soundingboard of a stringless piano, or the like. By this construction I form but one joint between the alarm-givingmedium and the bearing, and that joint of such construction as will avoid a harmful effect upon the transmission of the tone or vibrations. The entire support is made of one piece of proper metal, and the danger fromloss of vibrations, tone, or power due to imperfect or loosened joints,is obviated.

The accompanying drawings form a part of this specification, and represent what I consider the best means for carrying out my invention.

Figure 1 is a plan view; and Fig. 2, a detail section, showing the singlejoint and the gongbearing.

Similarletters of reference indicate like parts in both the figures.

A represents the volute gong, permanently welded or brazed to the head B, which has an aperture, 1), for the reception of a screw, 0.

D represents the body of the gong-support,

having a bearing-face for the gong-head and a threaded aperture, d, in which the screw 0 operates to hold the gong-head to the support body firmly. The support is provided with a spiral shank, E, which terminates with a perforated plate, F, which is secured to the proper bearing, which may be the back of the interior of a clock. The shank and body of the support are upon the same plane, and a slight bend in the plate F at its junction with the shank serves to hold the latter away from the bearing, as shown. The support D E F is cast in a single piece, and but a single joint exists in the device.

I attach much importance to the fact that by myinvention the support is one piece of cast bell-metal coiled in a small compass. The uniformity of texture due to casting favors a clear tone, and is much preferable in eflect .to any construction compounded of difi'erent metals.

I claim as my invention- 1. A gong-supporthavingan attaching body, a coiled or volute shank, and a securing-plate cast in a single piece, combined with a gong, whereby the gong is firmly secured to a clock or other object with but a single joint, as specifled.

2. The gong A and head B, welded or brazed together, as shown,oombined with the supportcomposed of the body D d, shank E, and plate F, cast in a single piece, and with the attaching-screw O, as and for the purposes specified.

In testimony whereof I have hereunto set my hand, at New York city, N. Y., this 3d day of March, 1882, in the presence of two subscribing witnesses.
